Flame

A flame (from Latin flamma) is the visible, gaseous part of a fire. It is caused by a highly exothermic reaction taking place in a thin zone. Some flames, such as the flame of a burning candle, are hot enough to have ionized gaseous components and can be considered plasma. There is, however, disagreement on this subject.

Famous quotes containing the word flame:

    If you would conquer Love, he must be fought
    At his first onslaught; sprinkle but a drop
    Of water, the new-kindled flame expires.
    Ovid (Publius Ovidius Naso)

    I feel my belief in sacrifice and struggle getting stronger. I despise the kind of existence that clings to the miserly trifles of comfort and self-interest. I think that a man should not live beyond the age when he begins to deteriorate, when the flame that lighted the brightest moment of his life has weakened.
    Fidel Castro (b. 1926)
